:To all whom, it may concern:

Be it known that we, GEORGE W. ARNOLD and WILLIAM C. HILL, citizens of the United States, residing at MountPleasant,in thecounty of Vestmoreland and State of Pennsylvania, have invented new and useful Improvements in Measuring-Pumps, of which the following is a specification.

Our invention relates to improvements in measuring-pumps adapted to be employed for drawing liquids from barrels, casks, &c., through the bung-hole, and it has for its objects to provideimproved means for measuring the liquid as it is drawn.

The invention consists in a pump which forces air into the barrel or cash to compress the air above the liquid therein, the tube inserted at its lower end in the liquid and serving as a channel for the liquid out of the cask or barrel, the measuring-vessel on the upper end of the tube to receive the liquid which is forced up the tube by the compression of the air, the spout in the side of the tube close to the bottom of the measuring-vessel, and the stop-cock in the tube at the inner end of the spout, whereby the liquid may either be forced into the measuring-vessel and then allowed to ilow out through the spout into a suitable vessel, or may be pumped directly out through the spout.

The invention consists, further, in the construction and arrangement of the parts to produce thesaid results, which are hereinafter more fully described in connection with the accompanying drawings, wherein- Figurel is a side view of the pump. Fig. 2 is a vertical section of thcsame. Fig. 3 is a detail view showing the measuring device. Fig. 4 is a detail view ofthe shell.

Referring by letter to the drawings, A designates a conical-shaped tube which is interiorly screw-threaded at the upper or outer end, and is designed to be tightly driven into the bunghole of the barrel or eask to be emptied. A shell, B, slightly conical in form, is screwed at the lower end in the upper end of this conical tube, and it is provided at the lower end with a lateral annular flange, O, which bears upon the upper end ofthe said tube A.

Packing a is interposed between the flange and the upper end of the tube to enable a tight joint to be formed. A tube, D, is inelosed at the upper end in the shell Rand the space between the tube and sides of the shell forms an air-chamber, E. It will be seen that the bottom of the shell is thus arranged at the upper end ofthe conical tube A,and perforations F F in the said bottoni establish a communication between the cylinder and the tube. The tube D extends below the lower end ofthe shell and passes down through the tubeAinto the barrel or cask to which the pump is applied. A small annular space, F', is left between the sides of the tube D and the lower edge of the conical tube to allow the air which is forced into the shell and tube to escapeinto the barrel. The tube D is formed in sections G G, the section G being attached rigidly to the shell in the position shown and described by means of solder or any other suitable means, andthe lower section, G, slides over the upper section. The lower end ofthe lower section is provided with a number of small notches, gg, (or small openings may be preferred,) through which the liquid in the barrel may pass when the lower end ol' the tube D is tightly pressed against the bottom of the barrel. A tube, H, slides in the upper end of the tube D, and the-latter is provided with a packing-box, I, to prevent leakage between the sides ofthe said tubes. The tube H is Vertically movable,for a purpose hereinafter more fully explained.

K represents a spout, which is attached to the side of the tube H, near the upper end and communicates with the interior thereof', and L represents a stop-cock, which is disposed within the tube H at the inner end of the said spout. The body ot' the stop-cock is provided with three openings, M, which communicate with each other, and these openings are adapted to align with the tube H above and below the stop-cock and with the spout K. Therefore it will be seen that the stop-cock may be arranged so as to form a direct pas sage up the tube H, or to establish communication between the lower portion of the said tube and the spout or the upper portion ofthe tube and the spout. The axial motion of the stop-cock is limited by any simple and wellknown device to prevent all of the said passages from being aligned at the same time,and, therefore, when the diametrically -opposite openings M M are aligned with the upper and lower portions of the tube H the other opening M is on the side of the stop-cock opposite to the spout, and therefore the latter is closed.

O represents a measuringvessel, which is attached to and communicates with the tube H at its upper end, and it is graduated to measure any desired quantities of liquids.

The shell B is provided on one side with a short tube or nipple, l?, to which is attached a flexible tube, R, adapted to convey the air from the pump to the shell. The drawings show a rubber bulb, S, connected to the free end of the rubber tube, which is of a similar construction to the bulb of a syringe, and this is the character of pump which we propose to use in connection with the small sizes of our device, as it will be found amply sufficient in strength and easily operated. In the large sizes of our pumps we will use compressingpumps of a different construction, which will have more power than that shown in the drawings.

The manner of applying this device to a barrel or cask will be readily understood from the foregoing. The conical tube is tightly driven into the bunghole after the bung has been drawn, the lower end of the tube Dis passed through the same, and the lower end of the shell is screwed into the outer end thereof after the sections of thc tube D have been so arranged as to reach to the bottom of the barrel. The barrel is air-tight, and as the air which is forced thereinto presses with great force upon the surface of the liquid the latter rises in the tubes D and H and passes into the vessel O. When the desired quantity of liquid has entered the said vessel, the stop-cock is turned to cut off the supply, and (if desired) allow the said liquid,which is now measured, to flow through the spout.

The stop-cock may be so arranged as to entirely cut off the lower portion of the tube H from the outside air, thus confining the odor of the liquid and preventing any injury to the liquid which might arise from exposure to the air. The pump and the air chambers and tubes are entirely isolated from the liquidconducting tubes, and therefore there is no danger of a stoppage. The tube H is formed vertically adjustable to enable the spout K to be raised or lowered to suit the height of the Vessel into which it is delivering the liquid.

Many forms of measuring-pumps are known; but in a great number of them the measurement is accomplished by revolving cylinders or revolving wings operating in a cylinder; but the accuracy of their measurement is necessarily affected somewhat by the condition of the instrument, and also by the condition of the liquid which is being measured. Further, they do not show plainly the means of measurement, and therefore their accuracy cannot be so well established. In our device, however, we use a measuring-vessel which may, if desired, be tested and stamped to attest its acc'uracy,'aud the 'condition of the 1nstrument or of the liquid cannot affect the accuracy of the measurement.

It will be seen that ifit is so desired the liquid may be pumped from the barrel directly through the spout into a suitable receivlngvessel.

Having thus described our invention, what we claim, and desire to secure by Letters Patent of the United States, is-

In a pump, the combination of the coni-` cal tube A, adapted to be secured in an opening in a barrel, the shell screwed in the outer end thereof and having an air-compressing pump attached thereto, the tube D, passing through the tube A and the shell, the tube H, having the spout K near its upper end, and the stop-cock L in the tube` II at the inner end of the spout, substantially as and for the purpose specified.
